This was my second time leasing a car at this dealership. Sam was very accommodating in getting me the best price to lease a 2018 GMC Terrain. The paperwork... was easy and there was never any stress or pressure to make a deal. Their professionalism is impeccable and Mike's training and followup after you drive away is very much appreciated. I highly recommend Colonial Buick GMC Watertown.

My brother in law recommended I try Colonial GMC in Watertown and talk to Brian. I am so glad I did! Aside from being super personable, Brian was very... helpful and efficient! Though I didn't go with the car I'd originally test drove- I explained what I was looking for, and was able to find it at another Colonial location. Brian had it delivered to Watertown the next day and after a quick test drive I was sold. Literally easiest car buying experience I've ever had. I never spent more than a half hour there, and walked away with my car registered and inspected after 2 days. This was the third dealership I visited and by far the best experience of all.

I sent a message through cars.com for a specific car. Brian scheduled a convenient time for me to come test drive the car. He had the car ready when I... arrived. The car was just what I wanted. Brian was great! I had to come back and ended up speaking with Tommy in service, who was also exceptional. Nice to meet these guys, super passionate and knowledgeable about cars and the business. I’ll definitely be back and will recommend Colonial Watertown!

I’d go back to Colonial anytime. No high pressure sales tactics from salesman Brian Mahan – just prompt answers to my many questions and honest, straightforward... negotiations. Brian left me alone to make my final decision but got back to me within minutes whenever I needed more information to make that decision. The price for my trade-in was more than fair and they gave me a great price on the vehicle I purchased. Even a competing salesman told me my deal from Colonial was great and recommended I take it!

This was the easiest process ever to get a new car, everyone was so helpful Brian was so accommodating and did all the hard stuff I don’t think the process... could have gone any smoother I highly recommend

Brian was really great throughout the process of buying my car. We had spoken on the phone ahead of time and he had the car ready for me to drive when... I arrived, and was there to greet me when I came back later to sign. He was very friendly and low pressure from the beginning. Really happy with my purchase.
